Arachni is a feature-full, modular, high-performance Ruby framework aimed towards
helping penetration testers and administrators evaluate the security of web applications.
It is smart, it trains itself by monitoring and learning from the web application's
behavior during the scan process and is able to perform meta-analysis using a number of
factors in order to correctly assess the trustworthiness of results and intelligently
identify (or avoid) false-positives.
Unlike other scanners, it takes into account the dynamic nature of web applications,
can detect changes caused while travelling through the paths of a web application’s
cyclomatic complexity and is able to adjust itself accordingly. This way, attack/input
vectors that would otherwise be undetectable by non-humans can be handled seamlessly.
Moreover, due to its integrated browser environment, it can also audit and inspect
client-side code, as well as support highly complicated web applications which make
heavy use of technologies such as JavaScript, HTML5, DOM manipulation and AJAX.
Finally, it is versatile enough to cover a great deal of use cases, ranging from
a simple command line scanner utility, to a global high performance grid of
scanners, to a Ruby library allowing for scripted audits, to a multi-user
multi-scan web collaboration platform.
